Section 2: Equipment
2.1 Bicycle
- Frame geometry: Standard road bicycle with traditional diamond frame. In draft-legal races, no time-trial or triathlon-specific frames are permitted. Seat tube angle and handlebar position must conform to UCI road geometry standards.
- Handlebars: In draft-legal races (Olympic, World Triathlon), clip-on aero bars, extensions, and triathlon-specific handlebars are prohibited. Drop handlebars with standard brake levers required. In non-drafting races, aero bars are permitted.
- Wheels: Standard road wheels. Disc wheels may be restricted in draft-legal races at the Technical Delegate's discretion (crosswind safety). Wheel diameter: 622 mm (700c) or 559 mm (26 in).
- Minimum weight: No minimum weight requirement (UCI's 6.8 kg minimum does not apply to triathlon).
- Mechanical condition: Bikes must pass a pre-race mechanical inspection. No loose components, broken spokes, or unsafe modifications.
2.2 Wetsuit
Wetsuit rules are based on water temperature measured at a depth of 60 cm, taken 1 hour before the race start:
- Mandatory: Water temperature below 16°C (60.8°F) for Olympic distance; below 14°C (57.2°F) for sprint distance.
- Optional: Between 16–20°C (60.8–68°F) for Olympic distance; between 14–20°C for sprint.
- Prohibited: Above 20°C (68°F) for Olympic distance; above 22°C (71.6°F) for sprint distance.
- Thickness: Maximum 5 mm at any point. Total coverage must not include gloves, shoes, or full-face coverage.
- Swim cancelled: If water temperature falls below 12°C (53.6°F) or exceeds 32°C (89.6°F), the swim may be shortened or replaced with a run segment (duathlon format).
2.3 Helmet
- CPSC, CE EN 1078, or equivalent-certified bicycle helmet mandatory.
- Helmet must be buckled and secured before the athlete touches or unracks the bicycle in T1.
- Helmet must remain buckled until after the athlete has racked the bicycle in T2.
- Violation of helmet rules results in a time penalty or disqualification.
2.4 Race Numbers and Timing
- Race number: Worn on the front during the run segment and on the back during the bike segment. Race belt permitted for easy switching.
- Timing chip: Ankle-mounted transponder provided by the organiser. Must be worn throughout the entire race. Timing mats at swim exit, T1 entry/exit, T2 entry/exit, and finish line record split times.
